Embodiment Construction

[0039]In accordance with the present disclosure, an endoscopic surgical clip applier including a clip counting mechanism is provided. Although disclosed for use in an endoscopic surgical clip applier, the clip counting mechanism is usable in a wide variety of surgical clip appliers. The clip counting mechanism is disposed within a handle assembly of an endoscopic surgical clip applier and includes a display gear, a counter switch, an escapement gear, and a gear pin. The display gear is rotatably disposed about a display gear post of the handle assembly and is rotatably biased by a biasing element mechanically coupled to each of the display gear and the display gear post. The display gear defines an outer surface having a contrasting color disposed on a portion thereof to indicate that the number of remaining surgical clips is low. The outer surface of the display gear defines a plurality of ratchet teeth that are radially spaced apart such that each tooth represents a predetermined ...

Abstract

A clip counting mechanism for use with a surgical clip applier includes a display gear rotatably supported within a handle housing of the surgical clip applier and including an outer surface having a plurality of numbers disposed thereon, a biasing element in mechanical communication with the display gear and rotatably biasing the display gear, a counter switch reciprocally disposed within the handle housing and defining a cam slot therethrough, and an escapement gear rotatably supported within the handle housing and defining a proximal end portion in mechanical communication with the display gear and a distal end portion in mechanical communication with the cam slot. Translation of the counter switch causes the cam slot to cam the escapement gear and selectively disengage and then re-engage the display gear to enable the display gear to rotate a predetermined angle of rotation.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of and priority to U.S. Provisional Patent Application No. 62 / 557,778 filed Sep. 13, 2017, the entire disclosure of which is incorporated by reference herein.BACKGROUNDTechnical Field[0002]The present disclosure relates generally to surgical clip appliers. More particularly, the present disclosure relates to endoscopic surgical clip appliers having a mechanism for indicating the number of remaining clips.Description of Related Art[0003]Endoscopic surgical staplers and surgical clip appliers are used for a number of minimally invasive or endoscopic surgical procedures. Typically in a minimally invasive surgical procedure, a tube or cannula device is extended into the patient's body through an entrance incision to provide an access port. The port allows the surgeon to insert a number of different surgical instruments therethrough for performing surgical procedures far removed from the incision.[0004]Durin...
